kv-value calculator

The kv value calculator determines the kv value for a desired flow rate. For safety reasons, the valve to be selected should have a kvs value that is about 30% above the required kv value (=minimum kvs value). This value is indicated under "kvs-valve".

Please note: decimal values can only be entered with a dot.
